SELECTING AN ENCLOSURE
There are several different enclosure designs for different applications.
The RUBICON subwoofers work very well in all the following enclosure
designs. It is up to you to select the specific enclosure that will work
the best for your particular application.
Infinite Baffle
Infinite baffle is the simplest type of subwoofer installation. In this type
of installation, the woofer(s) is mounted to a baffle which is then
mounted to either the rear deck or back seat of the vehicle. The best
results are achieved when the trunk area is virtually airtight and
isolated from the passenger compartment.
Sealed Enclosure
Sealed enclosures are relatively simple to build and
install, as all that is required is an airtight box. The
larger the sealed enclosure, the more the
performance resembles that of an infinite baffle
installation.
Vented Enclosure
Vented enclosures use a sealed enclosure with a
Pros Cons
• Good low frequency exten-
sion down to the tuning fre-
quency
• High power handling down
to the tuning frequency
• Higher output than sealed
enclosures
• Low power handling
below the tuning fre-
quency
• Almost no output
below the tuning fre-
quency
Pros Cons
• Very good low frequency
extension
• Very good transient re-
sponse
• High power handling
• Medium efficiency
Pros Cons
• Excellent low frequency extension
• Excellent transient response
• Uses almost no trunk space
• Lower power handling
• Low to medium efficiency

Sealed Bandpass (Cont'd)
• Rear = .50 sealed
Front = .40 @ 69 Hz (4” x
11.50” port)- Good bass
response in a small
enclosure.
• Rear = .40 sealed
Front = .50 @ 75 Hz (4” x
6.75” port)- High output in
50 to 80 Hz range -- Good
for Rap music.

vent or port in the box which is tuned to resonate at a specific
frequency.
Sealed Bandpass Enclosure
Sealed bandpass enclosures enclose both sides of the
woofer(s). An airtight enclosure is built around
the front and back of the woofer and one chamber is ported to a
specific frequency.
CALCULATING (NET) INTERNAL ENCLOSURE VOLUMES
When constructing any type of enclosure, you must be aware that the
outside dimensions DO NOT represent the true (Net) volume inside.
Such things as woofers, ports, thickness of enclosure material, dividing
walls, and any internal bracing will reduce the total amount of the
actual air space available. The following worksheet has been designed
to provide you with the necessary steps to accurately calculate the
absolute (Net) internal volume of any given enclosure.
Calculating Cylindrical Port Volume
1. Measure the outside diameter of the port and divide by 2 for the
radius.
2. Square the radius and multiply by 3.14 (π) to arrive at outside port
area.
3. Multiply the area by the length of
the port inside the enclosure for the
port volume.

ating frequencies
• Low power handling

• Poor low frequency

BUILDING THE ENCLOSURE
• Determine the dimensions of your enclosure.
• Be certain the box you have designed will fit into the location you have
chosen. Sometimes making a cardboard box with the same outside
dimensions is helpful.
• Use 3/4 inch thick Medium Density Fiberboard (MDF) or High Density
Particleboard. It is preferable to cut the wood with a table saw to ensure
straight, even joints. If a table saw is not available, a circular saw is
acceptable.
• Use a “T” square to verify precise right angle gluing.
• Use a high quality wood glue and air nails or wood screws to assemble the
enclosure. Elmer’s woodworker’s glue and Weldwood work well. To
guarantee an airtight box, seal each inside joint with silicone sealant.
• For Sealed Enclosures, stuff the chamber with 50-75% filling (approximately
1.5 pounds per cubic foot) of fiberglass insulation or Dacron.
• For Vented Enclosures, staple 1 inch thick fiberglass insulation or Dacron to
all walls of the enclosure except the baffle to which the woofer is mounted.
• Use the supplied gasket to seal the woofer in the enclosure and eight(8)
wood screws or T-nuts and bolts. Progressively tighten each of the bolts or
screws to prevent warping the woofer frame.
• Use slide-on connectors to attach speaker wires. Do not solder wires to the
provided terminals as this may cause damage to the factory wire
connection. This may also void the speaker’s warranty.
SUGGESTED ENCLOSURES
The following designs include a variety of enclosure sizes and types.
Each design has two frequency response curves; one showing
predicted
“In-Car” response, and the other showing “Half-Space Anechoic” (out-
of-car) frequency response. The performance difference between the
two curves is a result of the natural acoustics of an “average”
automotive environment. This “average” transfer function is only an
approximation of what you may expect to see in your car. Every car is
different. Each curve was generated using 2.83 Volts across both
voice coils in parallel and measured at 1 meter. Also, each frequency
response curve includes a 12 dB/octave low pass filter at 100 Hz for
sealed and vented enclosures and 200 Hz for bandpass enclosures.
The response curves can help you visualize relative performance
differences between designs. Read through the descriptions given for
each enclosure and select the one that suits your needs.
